NETED STATES PAUL JAWORSK'I, OF BISMABCKHUTTE, UEPER SILESIA.

Application filed August 26, 1921'.

To aZZ whom it may concern:

Be it known that I, PAUL JAwoRsKI, citizen of Prussia, residing at Bismarckhutte, Upper Silesia, have invented certain new and useful Improvements in Coking Chambers for Generators, of which the following is a specification.

This invention relates to a coking-chamber for gas producer furnaces or generators and adapted to be suspended therein so as to enable the raw coal to be primarily coked in the usual manner, the coke thereby obtained being continuously fed to the generator, so that the heat of the generator gases is utilized in coking the raw material.

According to the present invention'the coking chamber is so constructed that the product obtained by the coking process includes the tar substantially in its original state. For this purpose the material in the coking chamber is supported upon a plate spaced from and below the coking chamber, the space between the two forming an annular open inlet orifice for the generator gases, whilst forming a discharge orifice for the coking material supplied to the generator.

The preferred construction of the coking chamber is illustrated, by way of example, in the accompanying drawing and consists of a fixed casing a terminating above in an enlarged chamber 7) in which the gaseous products of the coking process are collected and discharged through a flue 0.

Below the lower edge of the casing a and at a predetermined distance therefrom is arranged a plate (Z which serves to support the material in the coking chamber. The material after passing through the coking chamber is discharged through the space i (between the plate (Z and casing a) into the generator by means of an ejector 7), which is fixed upon a shaft 11 carrying an agitator or agitators ,t' and hopper 6, so that they may be simultaneously rotated (as for example, by an upper worm wheel 0 on the hopper e and suitable worm gearing). The shaft n is journaled in a cross-bar g and the outer air is prevented from entering the rotary hopper.

The rotation of the hopper during the coking process causes the material to fall uniformly, thus preventing the formation of gas passages or pockets. The agitator 7 effects a similar result and the ejector h continuously discharges the material over the edge of the plate Z into the generator. Thus Specification, of LettersPatent.

the material is fed peripherally to the generator, so that a cratershaped charge in the generator is obtained, which is very desirable for efiicient gas production. The hot generator gases have constant and unrestricted access to the coking chamber and as the ejector it always keeps the space 2' clear, the effective area of the inlet aperture for the hot gases does not vary.

The hopper e is preferably arranged substantially low down (as illustrated) so that the gas chamber 6 is clear of the coal dust disturbed by the agitators, and the gas flue 0 free from troublesome dust accumulations, whilst the coal dust is also subjected to the coking process.

It is essential that the agitator or agitators should be low down and close to the ejector it so that the coal dust is not unnecessarily disturbed. The rotation of the hopper effects the levelling or settling of the upper portion of the charge in the coking chamber. Any gases which may collect in the upper portion of the hopper e are discharged into the gas chamber 6 through the openings m.

A feature of the coking chamber is that the discharge orifice i is constantly open and that control valves which are liable to crush the coal when violently closed, are avoided. The plate cl furthermore enables the coking chamber to be continuously charged from the bunkers by allowing the coal to slide down freely from the bunkers, which was heretofore not possible, in the case of generators in which the coking chamber charge rests on the generator charge, as the passage of the material through the coking chamber was dependent on irregularities and disturbances in the working of the generators and the latter could not be emptied for repairs without the whole contents of the bunkers )eing discharged.

Claims:

1. A coking chamber for generators comprising a casing, a feed hopper for the casing and a plate spaced from and below the lower end of said casing for supporting the contents thereof, the annular space thereby formed serving as an unrestricted inlet for the generator gases and as a discharge orifice for the coked material.

2. A coking chamber as specified in claim 1 having an ejector above and co-operating with the plate.

3. A coking chamber as specified in claim 1 having a shaft for the feed hopper, an

agitator fixed on said shaft, an ejector fixed on said shaft close to and co-operating with the plate and means for rotating-"said hopper;

4. A coking chamber forrgenerators comprising a substantially cylindrical casing enlarged at its upper end, a feed hopper supported in said upper end so as to form a narrowest chamber.
